The figure on the left has been transformed into the one on the right. which transformation does this show?
a) (x', y') = (y, x)
b) (x', y') = (x, -y)
c) (x', y') = (-x, y)
d) (x', y') = (-y, x)

Option B.

Step-by-step explanation:

The figure on the left has been transformed into the one on the right.

From the given diagram it is clear that the figure is reflected across x-axis.

If a figure reflected across x-axis, then the rule of reflection is

where, (x,y) is the ordered pair of image and (x,-y) is the ordered pair of preimage.

It means,

The given transformation is represented by .

Therefore, the correct option is B.

im alright what do you need

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
